る。That is, as shown in FIG. 5, the known color developer application device includes a color developer tank 5 for storing granular color developer S.
In the developer tank 50, there are provided a rotating developer carrying roller 52 and a replenishment roller 51 that is in pressure contact with the developer carrying roller 52. The developer carrying roller 52 and the replenishing roller 51 rotate with each other and are frictionally charged on their contact surfaces to positively charge the developer S, and the positively charged developer S is transferred to the developer carrying roller. The developer adheres to the circumferential surface of the color developer carrying roller 52 and is attracted toward the opposing roller 53 provided opposite the developer carrying roller 52 .

いた。A negative voltage is applied to the opposing roller 53, and the conveyor belt 5, which is an opposing electrode, is connected between the opposing roller 53 and a guide roller 55, 55 spaced apart from the rear side of the opposing roller 53.
4 is running. A support P supporting the color developer S, such as plain paper, is adsorbed and conveyed to the conveyor belt 54, and a positively charged granular color developer is formed at a position closest to the developer carrying roller 52 and the opposing roller 53. The agent S was transferred and adhered onto the support P to form a color developer layer m.

ができなくなってしまうといった問題点があった。However, in the conventional color developer coating device,
It adheres to the conveyor belt 54 at cuts in the support P such as plain paper that is being conveyed. At this time, if there is a hole in the conveyor belt 54, the color developer S adheres to the counter electrode roller 53 through the conveyor belt 54. Further, the color developer S may wrap around and adhere to the counter electrode roller 53, which is wider than the conveyor belt 54, from both sides of the conveyor belt 54. Once the color developer S is adhered, it is very difficult to remove it from the counter electrode roller 53 because it is a nonconductor, and therefore, the color developer S is deposited on the counter electrode roller 53. There was a problem that the uniformity of the gap between the counter electrode roller 53 and the support P was lost, making it impossible to uniformly apply the color developer S to the support P.

While being carried by the carrying roller 21 , it is conveyed toward a position facing the counter electrode roller 22 . Here, the developer S charged by the electric field generated between the counter electrode roller 22 and the developer carrying roller 21 is transferred and coated onto the support P by electrostatic force. The granular color developer S attached to the counter electrode roller 22 is conveyed from the cut in the support P through the conveyor belt 24 to a position facing the suction nozzle 31 as the counter electrode roller 22 rotates. Inside the suction nozzle 31, an airflow is generated from the suction nozzle 31 toward the color developer capture container 32 by the exhaust fan 34 arranged at the rear, and the color developer S adhering to the surface of the counter electrode roller is removed from the suction nozzle 7. It is sucked into the suction nozzle 31 by the air flow from the surface of the counter electrode roller 22 towards the internal negative pressure, and is captured by the capture filter 33 in the developer capture container 32 .

成された管３８が接続されている。FIG. 3 is a sectional view showing a schematic configuration of a second embodiment of the developer coating device 2. As shown in FIG. Components that perform the same functions as those in the first embodiment are given the same reference numerals and their explanations will be omitted. In this embodiment, the air conveyor 30 is formed of a tube 37 having a constriction 36 in the middle of a color developer capture container 32 which is provided with a capture filter 33 from a blower 35, and is arranged opposite to the counter electrode roller 22 in the constriction 36. A pipe 38 in which a suction nozzle 31 is formed is connected.

に運ばれる。According to such a configuration, the air flow sent from the blower 35 is accelerated by the tube restriction 36, and the pressure of the restriction 36 is reduced.
As a result, the inside of the suction nozzle 31 becomes negative pressure. Therefore, when the granular color developer S adhering to the counter electrode roller 22 approaches the position facing the suction nozzle 31 due to the rotation of the counter electrode roller 22, it is accompanied by the air flow from the surface of the counter electrode roller 22 toward the negative pressure of the suction nozzle 31. and is sucked into the suction nozzle 31. The absorbed color developer S is transferred to the color developer capture container 32
carried to.
